Re..: I use ordinary bulb, I'm not sure which wattage is the best, maybe 15 watt? Purpose-designed incubator bulbs? Just heard of that... any info about that? Start/stop temperature?

Hallo... everyone... straight to the problem, ok! I'm now building an egg incubator box, sized 100cm cubic. And i provide its heat with a set (4 pieces) light bulb. And now, what i like to know is: Any equation or formula to determine how long it took to warm up the whole box? Thanks...

okay... thanks a lot.. i think that's what i need...

Gearbox My mistake... :bugeye: I need info about gear calculation in a gearbox, the ratio calculation, if I'm not mistaken, and just a simple n short theory of a gearbox, if it's possible. Now I'm in my last year of my electrotechnik diplom study, I'm doing my final now, and i know null...

Hallo all! Anyone have any legitible info about gearbox? It's theory, it's ratio, it's calculation, everything about gearbox?
